If your career path is going nowhere, resign gracefully and switch careers. Research occupations to find out how much they pay and what their future outlook is (in the U.S., you can find this information in the Bureau of Labor Statistics Occupational Outlook Handbook). Find an occupation that pays well, and invest in the education and/or training to get you that job. Look for employers that offer competitive salaries and ample opportunity for advancement.

One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
